In what way was anything "stolen"? The content you refer to came with the original client. They reverse engineered the protocol and let existing clients connect to that. There's as much "stealing" going on here as with the Samba team reverse-engineering the SMB1/2/3 protocols. They weren't deceptively tricking users into thinking they were the real Battle.net servers, were they?

In a sane economy and legal regime, this would be allowed under open competition rules, in the same way that car manufacturers cannot prevent aftermarket mods to be sold and installed on their models. All these online platforms have big digital moats, and projects like these are offering alternatives to an otherwise captive audience. That's why Big Platform doesn't like it, but nothing about this has anything to do with stealing.
